Our summary today works with the article titled Regeneration towards suitability: A decision-making framework for determining urban regeneration mode and strategies from 2023 by Yan Liu, Liyin Shen, Yitian Ren, and Tao Zhou, published in the Habitat International journal.

This is a great preparation to our next interview with Alison Whitten in episode 266 talking about urban regeneration.

Since we are investigating the future of cities, I thought it would be interesting to see how to assess urban regeneration projects. This article introduces a two-step decision-making framework designed to guide urban regeneration by determining the most appropriate modes and strategies, using a case study in Chongqing, China, to demonstrate its effectiveness.

Welcome to today’s What is The Future For Cities podcast and its Research episode; my name is Fanni, and today I will introduce a research paper by summarising it. The episode really is just a short summary of the original paper, and, in case it is interesting enough, I would encourage everyone to check out the whole paper. Stay tuned until because I will give you the 3 most important things and some questions which would be interesting to discuss.

Urban regeneration is like breathing new life into decaying city areas, tackling challenges such as aging infrastructure, environmental decay, and social disintegration. The process aims to restore the functionality and aesthetics of urban spaces, enhancing the overall quality of life. Over time, cities face problems such as traffic congestion, inadequate public spaces, and outdated infrastructure, making regeneration an essential strategy for urban improvement. Through regeneration, cities not only rebuild but reimagine their future by addressing both physical and socio-economic needs.

Despite its potential, urban regeneration is not a straightforward process. It involves multiple stakeholders, including the government, private sector, and the public. Decisions must balance various goals such as economic revitalization, social cohesion, and environmental sustainability. Particularly in fast-growing nations like China, regeneration initiatives often falter due to insufficient planning and hasty demolitions that disregard cultural and historical values. This study sets out to offer a framework that ensures such efforts are suitable for their local context and sustainable for long-term urban health.

Urban regeneration strategies have evolved over time, with frameworks and methodologies developed to address the multi-dimensional needs of city renewal. Some approaches focus on physical improvements, such as upgrading infrastructure and revitalizing neighbourhoods, while others aim for broader socio-economic gains, including job creation and social integration. However, despite these efforts, many regeneration projects fall short due to their generic nature. They often overlook the unique local characteristics that make a one-size-fits-all approach inadequate for diverse urban environments.

The complexity of urban regeneration lies in its multifaceted nature. While much research has been dedicated to identifying appropriate strategies, there remains a gap in designing place-based solutions that account for a city’s specific social, economic, and physical conditions. Sustainable urban development requires more than just new buildings and infrastructure; it demands a nuanced understanding of local dynamics and constraints, such as financial capacity and historical conservation needs. This is particularly relevant in rapidly urbanizing regions, where decisions made today will shape the future cityscape for generations.

The study first looked at the existing urban regeneration literature and practices was conducted to understand the principles of sustainability in this context. Next, key variables influencing urban regeneration were identified, including socio-economic performance, physical conditions, and local constraints like financial capacity. A novel two-step decision-making process was then established to recommend suitable regeneration modes and strategies. Finally, a case study in Chongqing, China, was used to validate the framework.

Urban regeneration suitability depends on aligning regeneration efforts with sustainable development goals. This involves understanding social, economic, environmental aspects, and the physical conditions of an area. Tailoring regeneration to local needs ensures context-sensitive, sustainable outcomes, avoiding the risks of hasty large-scale demolitions that harm cultural heritage. The concept of regeneration intensity is also critical. In areas with significant historical and cultural assets, regeneration should be carried out incrementally to preserve the urban fabric. Conversely, in severely decayed areas with fewer restrictions, higher-intensity regeneration, including large-scale redevelopment, may be more appropriate. By balancing the intensity and scope of regeneration activities, cities can ensure that their development efforts are both effective and sustainable.

The two-step framework begins by assessing the current state of the city’s sustainable performance and physical conditions. This evaluation is based on various indicators such as economic growth, population density, building quality, and public facility access. Depending on the results, cities can choose one of three regeneration modes: improving physical conditions, enhancing sustainable performance, or an overall upgrade for areas with severe decay. The second step involves determining the appropriate intensity of the regeneration activities by factoring in local constraints, including financial capacity and historical preservation needs. This process ensures that each regeneration project is tailored to the specific needs of the area.

The framework was applied to nine districts in Chongqing, a rapidly growing municipality in Southwest China. Each district faced unique challenges, ranging from aging infrastructure to environmental degradation. By using the two-step decision-making framework, suitable regeneration strategies were identified for each district. For example, districts with decayed physical conditions but strong sustainable performance were recommended to focus on physical improvements, while districts with broader socio-economic challenges were advised to pursue comprehensive upgrades. This place-specific approach ensured that each area’s regeneration strategy aligned with its unique context and needs.

The case study demonstrated that the two-step framework effectively addressed the varied challenges across Chongqing’s districts. One district with significant historical assets, for example, adopted a low-intensity regeneration approach to preserve its cultural heritage, while another district, facing severe physical decay, was advised to pursue high-intensity redevelopment. The framework’s adaptability to local conditions proved essential in ensuring that regeneration efforts were both appropriate and sustainable.

Moreover, the framework helps policymakers avoid common mistakes such as one-size-fits-all solutions or excessive reliance on demolition. Instead, it encourages a balanced approach that considers long-term urban sustainability, historical preservation, and socio-economic revitalization. Through this tailored approach, cities can more effectively direct resources and efforts toward areas that will provide the greatest return on investment.

This practical framework for guiding urban regeneration efforts can ensure both suitability and sustainability. By incorporating a detailed understanding of local conditions and constraints, cities can avoid the pitfalls of poorly planned regeneration and work toward long-term improvements in both the built environment and residents’ quality of life. The two-step decision-making process not only improves the immediate outcomes of regeneration projects but also lays the foundation for sustainable urban development in the future.

Finally, as the most important things, I would like to highlight 3 aspects:

1. The two-step decision-making framework ensures urban regeneration efforts are tailored to local conditions, focusing on both sustainability and physical improvement.
2. Place-based approaches that consider local socio-economic, environmental, and historical factors are essential for effective regeneration.
3. Balancing regeneration intensity with local financial capacity and historical preservation needs leads to more sustainable and effective urban development outcomes.

Additionally, it would be great to talk about the following questions:

1. How can cities balance the need for rapid development with preserving their historical and cultural identity?
2. In what ways can local communities be more involved in deciding urban regeneration strategies?
3. How can we ensure that regeneration efforts benefit current and future residents equally?
